A guardianship/conservatorship is established by the Superior Court of Washington to protect and manage the personal and financial affairs of an individual due to temporary or long-term incapacity.
A trust is a agreement between an individual who funds the trust, the trustor, and an individual or entity designated to administer assets and income, the trustee, for the benefit of another individual, the beneficiary.
A probate is the administration of an individual’s assets after death. This can occur either under a will or “intestate” (i.e. without a will).
